Ignore?

Theres always 1 person on a server who spams you by /tpa or /msg.. Well there is for me, yes, you would tell them to stop, they might ignore, then you take it further and report it to the forums with a screenshot, but.. You want to play, and you are waiting for an admin or mod.. The person still spamming.. You do /ignore (name) for the time being.. Basically I'm asking for /ignore That would be great..
